I got a 98 dodge ram 1500 5.2. I replace the flex plate in it now i cant get it to start . Its got no fire . Could i have moved the crank shaft ps or unplug something

 

Probably damaged the crank sensor pulling/installing the trans. It's kind of a pain to get to, but, you are going to have to pull it, check it, and make sure none of the wiring harnesses got pinched between the engine and trans.

Thanks that is what I was thinking

 

Bring your arm with three elbows..... The crank sensor is a major pain. In more than one sense of the word.

 

I found the cps on the back of the block what or where does it plug in to

 

The crank sensor bolts to the block and plugs into the wiring harness via an unmistakable plug-in connector.

 

Thanks everyone i got it running it wsa the crank sensor. I took the wheel n fender linin5out n cut some of the sheet metal out of the way luckily i had it on a lift it was easier to get to that way

 

Did it have a bad experience with the trans R&R?

 

Not sure what you are asking

 

Did you give it a boo-boo while you were messing with the flexplate?
